To all whom it mag concern: V Be it known that 1,,Wumau 1D. Farms,

7 a citizen of the United States. of Amflrica,

. is my purpose residing at Jacksonville, inflthe county of Duval andState of Florida, have invented new and useful Improvements in ReleasingMechanism for Type-Writer. Type-Bars, 0 which the following is a s tion,

This invention relates to improvements in typewriters and has,particular applicaiion to a releasing mechanism for typewriter reys.

In carrying out the present invention, it to provide a mechanismwhereby, in the event of the type bars remaining in writing positionagainst the ac tion of the restoring means, as when'two keys are strucksimultaneously, the type bars may be restored to normal position.

Itis also my purpose to provide a. releasing mechanism whereby the typebars of typewriting machines may be restored ton'ormaly osition, in theevent of the same remaining in writing position against'the action ofthe restoring means, without necessitating the removal of, the typistshands from the key board. Or should a single type bar remain in writingposition against the platen on account of the type bars being too tightin their bearings, same may be restored to normal position.

Furthermore, I aim to provide a releasing mechanism for the type bars oftypewriting machines which may be readily applied to any type of machineand which will be simple in construction and reliable and efiicient inuse.

\Vith the above and other objects in view, the invention consists in theconstruction, combination and arrangement of parts here'- inafter setforth in and falling within the scope of the claims.

In the accompanying drawing, Figure 1 is a top plan view of a typewritershowing my invention applied thereto, and Fig. 2 is a side elevation ofthe same, parts being broken away. I

It is a well known fact that when two or more keys are strucksimultaneously, the type bars bind and remain in writing posi- .tionthereby necessitating the removal of the fingers from the key board toreach the type bars and pull the latter back onto the type bed. By meansof my invention, this inconvenience" is eliminated and the type bars arerestored to normal posit on without removing the hands from the keyboard of the machine.

Referring now to the. accompanying drawing in detail, the letter Aindicates a suitable form of typewriter including the frame 1, key board2, type bed 3, type bars 1 pivoted at one end for swinging move ment asusual and oonnectedto the type bar sub-lever5, the universal bar 6 bymeans of which the escapement mechanism is controlled, as is well known,the universalbar :a-rm 7, and the links 8 adapted to impart movement tothe bars through the medium of the type bar sub-levers.

My improved type bar releasing mechanism, in the present instance, ismanually controlled and comprises what may be termed a type bar throwarm 9, a type bar throw arm shaft 10 to which is rigidly fastened oneend of the type bar throw arm 9 and which is journaled for rockingmovement in suitable bearings carried by an appropiia'te part of thetypewriter, a pull lever 11 being fastened at one end to the shaft 10,While the opposite end thereof is connected through the medium of a link12 with the key lever 13 of the margin release key 14.

From the foregoing description taken in connection with the accompanyingdrawing, the construction, mode of operation and manner of employing myinvention will be readily apparent. Should two or more type bars sticktogether, incident to the keys thereof being struck simultaneously, thesame may be released and returned to the type bed under the action ofthe usual restoring means, .this relcaseof the type bars beingaccomplished-by depressing the key 14, whereby a rocking motion istransmitted to the shaft- 10, through the medium of the link 12 and pulllever 11, with the effect to swing the type bar throw arm 9 intoengagement with the universal bar 6, thereby striking the type barsub-levers 5 whereby the type bars are moved out of contact with oneanother and to normal position under the action ot the'restoring means.0

1n the" 'present form of my invention, I

have shown the margin release key 14 of the typewriter as employed foractuating my improved releasing mechanism. It will be understood,however, that this releasing mechanism may be actuated by any othersuitable means. a 1

While I have herein shown and' described one particular embodiment of myinvention I by way of illustration, I wish it to be under stood thatI donot confine myself to the details of construction herein described anddelineated, as modification and variation may be made within the scopeof the aims.
